    摘要： A method comprises creating calibration data using a first control circuitry of an apparatus, replacing the first control circuitry with a second control circuitry in the apparatus, and operating the apparatus with the second control circuitry using the calibration data. As an example, the apparatus may be a disc drive. The second control circuitry may be substantially similar to the first control circuitry such that calibration measurements using the first control circuitry are applicable to the second control circuitry. The first control circuitry may be included in a circuit board that is replaced with a second circuit board including the second control circuitry. In an exemplary embodiment, the second circuit board may include different and/or additional components relative to the first circuit board, such as integrated video inputs and/or video control circuitry.

    摘要： Satellite communications are carried out using the Data Over Cable Interface Specification (DOCSIS). Satellite modems are notified of upstream channel congestion by inserting a congestion notification message in a medium access protocol (MAP) message for the upstream channel. Specifically, the congestion notification message is inserted in an unused field of the MAP message, such as the explicit congestion notification (ECN) field. The MAP message can also carry other characteristics of the upstream channel, including priority threshold, multicast access burst availability, and available bandwidth.

    摘要： A system includes a broadcast overlay network including a ring topology. The ring topology includes a first network ring and a second network ring that is coupled to the first network ring via at least one cross-connect element. The ring topology is adapted to carry broadcast traffic from a network. The system also includes a digital subscriber line access multiplexer (DSLAM) having a line interface and a network interface. The network interface is in communication with the broadcast overlay network via the second network ring. The DSLAM is adapted to receive a request for a particular video channel from a customer premise via the line interface and to deliver the particular video channel from the network interface to the line interface.

    摘要： The present disclosure is directed to a system and method of correcting video data errors. In a particular embodiment, the method includes receiving a plurality of Internet Protocol (IP) video data packets at a generator of a video acquisition system. The method also includes calculating a first error correction code corresponding to a first error profile and generating a first forward error correction (FEC) packet to produce the first error correction code. The method also includes calculating a second error correction code corresponding to a second error profile and generating a second FEC packet to produce the second error correction code. Further, the method includes transmitting a stream of data packets including the plurality of IP video data packets, the first FEC packet and the second FEC packet, to a re-generator of an Internet Protocol video transport system, where an arbitrator of the re-generator identifies an error in the plurality of IP video data packets and selects one of a plurality of inverse FEC functions to correct the error.

    摘要： An apparatus and method for winding a sheet of aligned parallel yarns onto a beam is described. The beam winder utilizes a circularly arced yarn spool rack that feeds each yarn to an alignment comb through associated guide tubes. The distance between each spool of yarn and the alignment comb is substantially the same for all spools of yarn, thereby equalizing the force necessary to pull them to the comb. Next, the aligned sheet of material is preshrunk using heated rollers and wound onto a beam. Multiple speed controlled stepper motors are utilized to maintain a constant low level of tension in the sheet during the shrinking process. After shrinkage, the tension level of the yarn sheet is increased as it is wrapped onto the beam. A turntable that supports two or more beams is provided to facilitate the rapid switching of beams once one beam has become full.

    摘要： A direct division modulator is provided. The direct division modulator includes a symbol mapper converting the input data from a binary bitstream to a desired frequency deviation, such as where the frequency deviation data encodes the information from the bitstream. A converter generates a divide value using the desired frequency deviation information, and a summer adds an average value to the divide value. A converter quantizes the divide value and shapes quantization noise associated with the quantized divide value. A divider modulates a reference signal with the quantized divide value and generates an output signal.
